State 2 function of gizzards in poultry animals

1. Grinding and breaking down food: One of the main functions of the gizzard in poultry animals is to grind and break down food particles into smaller pieces. The gizzard is a muscular organ that contains small stones or grit that help birds in the grinding process. This mechanical action helps in digestion and absorption of nutrients from the food.

2. Storage of food: Gizzards also act as a storage organ for food in poultry animals. They can hold partially digested food until it is ready to be further processed in the digestive system. This helps in maintaining a constant supply of nutrients for the bird's energy needs.
